W WB 'e mmm Application filed July 6, 1918.

To all whom it may conccrn: i

Be it known that I, LOUIS MAYER, a citizen of the United States, and resident of Kaukauna, in the county of Outagame and State of Wisconsin, have invented certain new and useful Improvements in Power- Hammer Guide-Heads; and I do hereby declare that the following is a full, clear, and exactdescription thereof.

The present invention relates to new and useful improvements in power hammers more particularly of that type including a reciprocal ram'carried in the guide head above the anvil and actuated either by a rock-lever within the guide head, or by a pitman connection with a superclosed crank wheel.

It is primarily the object of my invention to provide means for taking up looseness in the guide head mounting for the ram due to the wear occasioned by continued movement of the ram, and it is more specifically an object to provide a means for adjusting the walls of the guide head to vary the space between the guide channels thereof.

A further object resides in the provision of an adjusting means of this nature which is of exceedingly simple Construction and which may be manipulated in a most ready manner.

With the above and other objects and advantages in view, the invention resides more particularly in the novel combination, formation and arrangement of parts hereinafter described and pointed out in the appended claim.

In the drawings:

Figure 1 is a vertical sectional view through the guide head of a power hammer including a rock-lever actuated ram, and showing my improved adjusting means associated therein.

Fig. 2 is a horizontal sectional view through the lower portion on the line 2-2 of Fig. 1.

Fig. 3 is a horizontal sectional view through the guide head of a power hammer more particularly of that type enrbodying a. pitman actuated ram.

Referring now more particularly to Figs.

spectively the front and rear walls and 7 designates the side walls of the hollow standard of -a power hammer embodying my, in* vention. To form the .guide head for the ram 8, which has vertical* beveled guide flanges 9 at its sides, the side walls 7 of the standard are eXtended upwardly past the walls 5 and G and directed laterally, with their free ends enlarged and provided with opposed V-shaped channels 10 receiving the guide fianges 9 of the ram. The ram is thus held for vertical slidng movement and is actuated by a rock-lever 11 intermediately pivoted between the laterally extended side walls and loosely connected with the ram. The extended side wall portions which form the guide head have slight relative movement due to flexure of the walls, and this movement is utilized to compensate for wear of the guide fl-anges and channel. channel ends of the extensions are held against relative movement by upper and lower bolts 12 passed therethrough and threaded on these bolts at both sides of each wall extension are holding nuts 13. Thus, should wear occur 'between the guide flange of the ram and the Channels, the nuts may be adjusted to draw the walls together and take up such wear. p

Referring now more particularly to Fig. 3, in that type of power hammer embodying a crank wheel and piston, the ram 14: is slidably mounted in the outer' end of a web 15 projecting forwardly from the body frame, the outer end of this web being enlarged and provided with 'a clove-tail channel 16 in its outer face receiving beveled guide flanges 17 of the ram. In applying my invention to this type of ram mounting, the web 15 is thickened inwardly of its said thickened end and is longitudinally slit whereby the consequently divided portions of this thickened end may have relative move ment. This relative movement of the channel portions is controlled as in the structure of Figs. land 2 Hoy bolts 18 passed therethrough and provided at both' sides of the divided end portions with seuring nuts 19.

What is claimed is:` j

In a power hammer, the combnation with 'a body frame portion, of space& wall por- The i tons extendng integmlly then-?fmin` and otherwise free, guide Channels at the outer ends of said Wall portons, a ram sldable in said guide Channels, and bolts passed through said Wall portons and rgdly adjustzbly connected therewth Whereby to hold the Channels in rgd relaton and to provide for adjustment of the Channels to ward and away from each other by flexure of the Wall powtons. 10

In testimony that I claim the foregoing I have hereunto set my hand at Kaukaua,

in the County of Outagzme and State of WVsconsn.
